75% of Healthcare Organizations Fall for Ransomware Attacks – Sophos Report

Sophos, a global leader in innovating and delivering cybersecurity as a service, on Thursday shared its sector survey report, “The State of Ransomware in Healthcare 2023,” which revealed that, among those organizations surveyed, cybercriminals successfully encrypted data in nearly 75% of ransomware attacks.

This is the highest rate of encryption in the past three years and a significant increase from the 61% of healthcare organizations that reported having their data encrypted last year.
In addition, only 24% of healthcare organizations were able to disrupt a ransomware attack before the attackers encrypted their data—down from 34% in 2022; this is the lowest rate of disruption reported by the sector over the past three years.
“To me, the percentage of organizations that successfully stop an attack before encryption is a strong indicator of security maturity. For the healthcare sector, however, this number is quite low—only 24%. What’s more, this number is declining, which suggests the sector is actively losing ground against cyberattackers and is increasingly unable to detect and stop an attack in progress.
“Part of the problem is that ransomware attacks continue to grow in sophistication, and the attackers are speeding up their attack timelines. In the latest Active Adversary Report for Tech Leaders, we found that the median time from the start of a ransomware attack to detection was only five days. We also found that 90% of ransomware attacks took place after regular business hours.
“The ransomware threat has simply become too complex for most companies to go at it alone. All organizations, especially those in healthcare, need to modernize their defensive approach to cybercrime, moving from being solely preventative to actively monitoring and investigating alerts 24/7 and securing outside help in the form of services like managed detection and response (MDR),” said Chester Wisniewski, director, field CTO, Sophos.
Additional key findings from the report include:
· In 37% of ransomware attacks where data was successfully encrypted, data was also stolen, suggesting a rise in the “double dip” method
· Healthcare organizations are now taking longer to recover, with 47% recovering in a week, compared to 54% last year
· The overall number of ransomware attacks against healthcare organizations surveyed declined from 66% in 2022 to 60% this year
· Compromised credentials were the number one root cause of ransomware attacks against healthcare organizations, followed by exploits
· The number of healthcare organizations surveyed that paid ransom payments declined from 61% last year to 42% this year. This is lower than the cross-sector average of 46%
“In 2016, the Red Cross Hospital of Córdoba in Spain suffered a ransomware attack that reached servers and encrypted hundreds of files, medical records and other important patient information. It was a major disruption to our operations and interfered with our ability to care for our patients.

“The stakes are high in ransomware attacks against healthcare organizations—and attackers know that—meaning we’ll always be a target. After this ransomware attack, we worked hard with Tekpyme to bolster our defenses, and now we have reduced our incident response time by 80%.
“I think the industry as a whole is making improvements, but there is still work to do, because of the constantly changing nature of cybercrime.
“Hopefully healthcare organizations can leverage the help that is available from security vendors such as Sophos to prevent a very real ‘threat to life’ if systems go offline due to a ransomware attack,” said José Antonio Alcaraz Pérez, head of information systems and communications at Cruz Red Andalusia in Spain.
“Cyberspace today is ripe with technically sophisticated actors looking for vulnerabilities to exploit. What all this translates to is a multidimensional cyberthreat of actors who have the tools to paralyze entire hospitals. Partnering with the private sector is critical to our mission. The information [they] share has real-world impacts and can save real businesses and real lives,” said Christopher Wray, FBI Director.
Sophos recommends the following best practices to help defend against ransomware and other cyberattacks:
· Strengthen defensive shields with:
o Security tools that defend against the most common attack vectors, including endpoint protection with strong anti-ransomware and anti-exploit capabilities
o Zero Trust Network Access (ZTNA) to thwart the abuse of compromised credentials
o Adaptive technologies that respond automatically to attacks, disrupting adversaries and buying defenders time to respond
o 24/7 threat detection, investigation and response, whether delivered in-house or by a specialized Managed Detection and Response (MDR) provider
· Optimize attack preparation, including regularly backing up, practicing recovering data from backups and maintaining an up-to-date incident response plan
· Maintain security hygiene, including timely patching and regularly reviewing security tool configurations

Telcos Recover N2 Trillion following Crackdown on Indebted Subscribers

Telecommunications operators in Nigeria have reportedly recovered over N2 trillion from subscribers in a sweeping debt recovery campaign that has left millions unable to make calls due to unpaid airtime and data loans.

The aggressive enforcement follows new compliance requirements introduced by the Federal Competition and Consumer Protection Commission (FCCPC), which telecom operators reportedly failed to meet, according to The News Chronicle.
This led to the suspension of airtime and data lending services and triggered a nationwide push to recover outstanding debts.
As part of the measures, indebted subscribers have had their lines restricted from making calls until their loans are fully repaid.
The move has disrupted daily life across Nigeria, particularly for small business owners and workers who depend heavily on mobile connectivity.
The lending service, valued at over N400 billion annually, has long served as a financial lifeline for many Nigerians, especially those without access to formal credit systems.
However, its sudden suspension has forced users to seek alternative means to clear their debts or abandon their lines altogether.
Meanwhile, a legal dispute involving Nairtime Nigeria Limited has added another layer of complexity.
A Federal High Court in Abuja recently ordered MTN Nigeria and Airtel Nigeria to maintain access to key telecom infrastructure, including USSD and SMS services linked to the platform.
Despite the court’s interim injunction, lending services tied to the platform remain unavailable, indicating ongoing tensions between telecom providers, regulators, and fintech firms.
Industry stakeholders warn that the disruption highlights deeper challenges within Nigeria’s digital economy, where telecom infrastructure increasingly supports financial services.
Millions of users who rely on airtime and data borrowing remain disconnected, caught between regulatory policies, corporate disputes, and the need for affordable communication.
As pressure mounts, both regulators and telecom operators are expected to seek a resolution that balances consumer protection with uninterrupted access to essential digital services.

Organized Criminals Plunder Telecom Infrastructure across Nigeria, Cause Service Disruptions

Theft and vandalism of critical infrastructure have reached crisis levels in Nigeria, as hundreds of generators and batteries are being stolen from base stations across the country.

Vandals and criminal gangs target power-related assets and cables, creating significant operational damage, with over 50,000 cases reported over five years, leading to network shutdowns.
A newly released data from the Nigerian Communications Commission (NCC) showed that 656 critical power assets were stolen from telecom sites across the country in 2025 alone.
According to the NCC data, a total of 152 generators and 504 batteries were stolen within the year, raising fresh concerns about network reliability and quality of service.
The infrastructure theft debacle is not limited to generators and batteries alone as rampant cases of cables and diesel thefts are also reported.
This vandalism causes massive disruptions in electricity and connectivity, resulting in significant financial losses and hindered business operations nationwide.
Hardest Hit States are; Delta, Rivers, Cross Rivers, Akwa Ibom, Ogun, Ondo, Edo, Lagos, Kogi, FCT, Kaduna, Niger, Osun, and Kwara.
Operators like MTN Nigeria said it spent over N1 billion on security and repair in 2025 due to 9,218 fiber cuts.

According to him, MTN Nigeria continues to integrate ESG principles into its core operations to drive growth, manage risk, and unlock new opportunities.
Beyond its tax contributions, the company recorded notable environmental milestones, including a 6.4 per cent reduction in Scope 1 and 2 greenhouse gas emissions relative to its 2021 baseline.
It also secured a ‘B-’ rating for climate change and ‘C’ for water security from the Carbon Disclosure Project (CDP), while over a third of its top suppliers by spend have committed to its net-zero ambitions.
On the social front, MTN Nigeria expanded its network coverage to 93.7 per cent of the population, improving connectivity nationwide.
Female representation within its workforce rose to 43.4 per cent, while N2.7bn was invested in corporate social investment initiatives, impacting more than 534,000 individuals.
The company also launched its “Help Children Be Children” programme to promote child online safety and awareness.
In terms of governance and business performance, MTN Nigeria reported a Reputation Index of 80.2 per cent, exceeding its benchmark, and achieved a sustainability rating of 3.7 out of 4.0 from ESG rating firm Risk Insights.
The firm further strengthened local economic participation by directing 62 per cent of its procurement spend to domestic suppliers, an increase from the previous year.
Tobechukwu Okigbo, chief Corporate Services and Sustainability Officer, said the company remains focused on delivering measurable, positive outcomes across its operations.
He noted that MTN Nigeria conducted a comprehensive “True Value Assessment” covering its economic, social, and environmental impacts between 2021 and 2024, alongside a double materiality assessment to better align its strategy with stakeholder priorities.
Okigbo added that the company also hosted its inaugural “Facts Behind the Sustainability Report” session at the Nigerian Exchange Limited (NGX), aimed at enhancing transparency and stakeholder engagement.
MTN Nigeria said it will continue to prioritise sustainable innovation, inclusion, and governance excellence, reiterating its commitment to ensuring broader access to the benefits of a modern, connected life while delivering long-term value to shareholders and society.
